BUFFlNG-WHEEL FOR REFINISHNG EDGES OF SHOE-SOLES.

Specification of Letters Patent.

'Patented oct. 31, 1905.

To all whom/ it may concern:

Be it known that I, WILLIAM B. ARNOLD, a citizen of the United States, residing at North Abington, in the county of Plymouth and State of Massachusetts, have invented an Improvement in Buffing-Wheels for Refinishing Edges of Shoe-Soles, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like arts.

p My invention is a machine for refinishing the edges of boot or shoe soles, being particularly intended for putting them in proper condition after they have been marred in handling in the iinishing processes of manufacture, although my invention may be used for finishing the edges entirely without employing any edge-setting machine.

While passing through the inishing stages and after the edges of the sole have been properlyiinished or burnished the handling usually mars and blurs the high polish, so that it becomes necessary to reiinish said edges. For this purpose it has been customary to einploy polishing-wheels of waXed felt having continuous polishingedges, great caution and skill being necessary in using these felt wheels, becausevof their liability to burn the leather and remove lthe blacking, thereby taking 0H the gloss and injuring the shoe. Even when the operator is cautious and handles the shoe delicately these felt wheels will sometimes remove the blacking and leather sufliciently to injure the shoe.

My invention obviates the aforesaid disadvantages and produces an excellent polishing medium, re uiring practically no skill in its use, and resi es in providing air spaces or pockets in the felt wheels which maintain the surface of the leather comparatively cool and produce a fan-like action, while at the same time the successive shoulders produce animpact effect on the leather and felt which facilitates the nishing action of the machine. I employ also a felt guard which maintains the shoe in proper position and cooperates with the sole in giving the best results.

My invention will be more fully understood in the course of the following description, taken in connection with the accompanying drawings, in which I have shown a preferred embodiment of my invention.

In the drawings, Figure 1 shows in front elevation the complete embodiment of my invention. Fig. 2 is a viewin side elevation of the felt wheel and guard, and Fig. 3 is a vertical cross-section thereof. l

On a suitable pedestal a is mounted a shaft a, operated by a pulley a2 and belt a3 from a driving-pulley a4 on the main shaft a5, provided With fast and loose pulleys a a7. At its outer end the shaft a carries the felt burnisher b, which constitutes the main feature of my invention. This burnisher or wheel consists of a disk t', of thick heavy felt, and a thin disk b2 at the inner side thereof larger in diameter, so as to provide a projecting iiange b3. The disk or Wheel t is thick and relatively soft, while the disk b2 is quite stiff, so as to withstand lateral pressure, while yet presenting a soft edge to bear against the bottom of the sole whose edge is being refinished by the disk b. At frequent intervals the disk b has transverse edge portions removed to provide air-pockets b4, so that when the wheel is rotated at low speed these pockets carry a sufiicient quantity of cooling-air to prevent any injury to the leather or blacking and to aid in maintaining and renewing the gloss and finish of the sole edge. The main driving-shaft is also provided with a pulley as and belt a, engaging a pulley am for driving a cleaning-brush a on a shaft (L13.

In use the operator irst applies a little wax to the edge of the wheel b and holds the shoe against the same in usual manner; but instead of being obliged to exercise great caution and nicety of handling I have found that by reason of the provision of the air-pockets the polishing progresses Without liability of injury to the shoe and is accomplished more rapidly and uniformly. The operator can move the edge surface of the sole much more rapidly over the wheel, so that a greater output is insured by my invention. The main advantage, however, is in the avoidance of the necessity of extreme care lest the sole edge should be injured instead of renished.

Many changes in the form of the air-pockets and in the cushion-flange may be resorted to without departing from the spirit and scope of my invention as set forth in the following claims, taken in connection with this description.

I-Iaving described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. A sole-ed e-iinishin wheel, consisting of a thick, soli felt whee having a series of narrow, air-pockets in its periphery for re- IOO venting burning and damage to the sole e ge.

2. A sole-edge-nishing Wheel, having-a ,Wide periphery of solid yie1ding'fe1t, aand arse-v Yflangeengaging the bottoni of he sole as the vzegge @thereof 'I engages said fbroad Vpolishing e ge.

flntestimony whereof l have Vsigned my I5 name to this specification in the presence of `two `subscribing Witnesses.
